Hydroacylation of 1-alkene with a heteroaromatic aldehyde such as pyridinecarboxaldehyde, thiophenecarboxaldehyde and furfural derivatives under cocatalyst of Wilkinson's complex and 2-amino-3-picoline gave poor yield of hydroacylated product. The addition of a catalytic amount of bis(cyclopentadienyl)zirconium dichloride or bis(cyclopentadienyl)titanium dichloride as an additive dramatically increased the yield of the hydroacylated ketone product.
